Despite its weak revenue growth guidance for this quarter, Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) might see stronger growth from next quarter thanks to its next-generation packaging technology.
Analysts said the integrated fan-out (InFO) packaging could help TSMC beat rival Samsung Electronic Co in winning more A10 application processor orders from Apple, because the technology has the advantage of lower costs, higher speed and thinner form, compared with conventional flip chip packaging.
The InFO technology is at least 20 percent cheaper than existing packaging technology, Yuanta Securities Investment Consulting Co (元大投顧) analyst George Chang (張家麒) said in a report issued on Tuesday last week.
TSMC already has a complete InFO portfolio aimed at different package sizes and applications, he said in the report.
In a quarterly earnings conference call with investors on Thursday last week, TSMC co-chief executive officer C.C. Wei (魏哲家) said the company has almost completed equipment installation at a facility in Taoyuan’s Longtan District (龍潭) in preparation for InFO volume production.
“We expect to complete customer product qualification shortly and will be ready for volume production this quarter,” Wei said at the conference.
In addition to high-volume preparation and product qualification, “we are working on yield improvement and cost reduction,” Wei said.
TSMC, the world’s largest contract chipmaker, is sticking to its original estimate that InFO technology would contribute about US$100 million revenue in the final quarter of this year, Wei said.
“InFO will be a powerful technology to catch growth opportunity in both mobile and IoT [Internet of Things] markets,” he said.
Apple is widely speculated to unveil its new iPhone in the second half of this year, which analysts think is likely to drive TSMC’s business.
Daiwa Capital Markets Inc semiconductor analyst Rick Hsu (徐稦成) said that InFO is key to TSMC forging a closer relationship with Apple and adding momentum to future growth.
Hsu said TSMC demonstrated a solid track record of execution for A9 processors and its new InFO packaging is “another key to gaining traction with Apple.”
Researchers at Daiwa estimated that Apple’s order split for A9 processors was 45 to 55 percent for TSMC and Samsung, but this time the Taiwanese chipmaker could claim a lead in A10 processor orders against its South Korean rival, Hsu said in a report this week.
The increase in A10 orders is expected to help TSMC accelerate its revenue growth at “an above-seasonal” pace of 14 percent in the third quarter this year from the second quarter, Hsu said in a report on Thursday last week.
TSMC forecast revenue growth for the second quarter would only be between 6 to 7 percent from the previous quarter.
Following a significant volume ramp-up in the final quarter this year, the revenue contribution from InFO packaging could total US$300 million this year, Hsu said.
Industry watchers have said that TSMC’s interest in supporting the fan-out wafer-level packaging — which eliminates the need for the bumping process and it does not use the substrate in the flip chip process — shows that the company’s ambition to have a complete application processor, microcontroller units and graphics processing unit manufacturers, as well as semiconductor front-end process manufacturing and full back-end packaging services.
TSMC is the first chipmaker to commercialize the InFO technology for its 16 nanometer chips, providing both front-end and back-end services, Chang said, adding that it is becoming more difficult to solely rely on front-end tech node migration to drive better performance and cost.
Aside from Apple, other smartphone chip vendors are likely to follow suit in adopting InFO packaging along with TSMC’s 16 nanometer technology, if they are looking for a better solution for cost-sensitive, mid-end handsets, he said.
Shares of TSMC closed 1.24 percent lower at NT$159.5 on Friday in Taipei trading, after the company reported net profit fell 18 percent year-on-year in the first quarter.
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) would not produce its most advanced technologies in the US next year, Minister of Economic Affairs J.W. Kuo (郭智輝) said yesterday. Kuo made the comment during an appearance at the legislature, hours after the chipmaker announced that it would invest an additional US$100 billion to expand its manufacturing operations in the US. Asked by Taiwan People’s Party Legislator-at-large Chang Chi-kai (張啟楷) if TSMC would allow its most advanced technologies, the yet-to-be-released 2-nanometer and 1.6-nanometer processes, to go to the US in the near term, Kuo denied it. TSMC recently opened its first US factory, which produces 4-nanometer
PROTECTION: The investigation, which takes aim at exporters such as Canada, Germany and Brazil, came days after Trump unveiled tariff hikes on steel and aluminum products US President Donald Trump on Saturday ordered a probe into potential tariffs on lumber imports — a move threatening to stoke trade tensions — while also pushing for a domestic supply boost. Trump signed an executive order instructing US Secretary of Commerce Howard Lutnick to begin an investigation “to determine the effects on the national security of imports of timber, lumber and their derivative products.” The study might result in new tariffs being imposed, which would pile on top of existing levies. The investigation takes aim at exporters like Canada, Germany and Brazil, with White House officials earlier accusing these economies of
GREAT SUCCESS: Republican Senator Todd Young expressed surprise at Trump’s comments and said he expects the administration to keep the program running US lawmakers who helped secure billions of dollars in subsidies for domestic semiconductor manufacturing rejected US President Donald Trump’s call to revoke the 2022 CHIPS and Science Act, signaling that any repeal effort in the US Congress would fall short. US Senate Minority Leader Chuck Schumer, who negotiated the law, on Wednesday said that Trump’s demand would fail, while a top Republican proponent, US Senator Todd Young, expressed surprise at the president’s comments and said he expects the administration to keep the program running. The CHIPS Act is “essential for America leading the world in tech, leading the world in AI [artificial
REACTIONS: While most analysts were positive about TSMC’s investment, one said the US expansion could disrupt the company’s supply-demand balance Taiwan Semiconductor Manufacturing Co’s (TSMC, 台積電) new US$100 billion investment in the US would exert a positive effect on the chipmaker’s revenue in the medium term on the back of booming artificial intelligence (AI) chip demand from US chip designers, an International Data Corp (IDC) analyst said yesterday. “This is good for TSMC in terms of business expansion, as its major clients for advanced chips are US chip designers,” IDC senior semiconductor research manager Galen Zeng (曾冠瑋) said by telephone yesterday. “Besides, those US companies all consider supply chain resilience a business imperative,” Zeng said. That meant local supply would
